Abstract
A molten metal bath composition analysis system includes: a laser oscillator that oscillates a laser beam; a cylindrical probe that includes an opening end immersed in a molten metal bath, supplies an inert gas toward the opening end, and guides the laser beam to the opening end to irradiate a molten metal with the laser beam; and a detector that detects and spectroscopically analyzes plasma emission of the molten metal caused by the irradiation with the laser beam, wherein at least one of the position of the opening end of the cylindrical probe in the molten metal bath and the angle of the cylindrical probe with respect to a vertical direction can be controlled.
